How The Mythbusters Accidentally Punched a 15cm Cannonball Hole in a People Carrier

The cannonball was supposed to blast through an array of water barrels and a cinderblock wall. Supposed to. Instead it hit the wall, a hill and Jasbir Gill's Toyota Sienna. Now do you see why they tell you not to try this at home?

The accident occurred Tuesday afternoon at an Alameda County Police bomb range adjacent to Santa Rita Jail, about a half mile outside of Dublin, California (not Ireland). The gun had lifted slightly from its intended position just before it fired, putting the steel round over the water barrels, off the hillside and through the van's front passenger window. Nobody was injured, though Gill was understandably peeved. "I'm angry and lucky to be alive. Anybody could have been hit by this," he told the San Francisco Chronicle.

Side note: Do they make apology cards for this sort of thing? Like, "Sorry I blew out your windows from a half-mile" or "I totally didn't think that was plugged in" or "Who expected alligators down there? Not me." They should. [SFGate]
